The actor twisted his knee last week during filming in Atlanta, Georgia, according to WENN.
He allegedly insisted on continuing filming in order to keep the schedule on the movie running smoothly.
He told USA Today: "I twisted my knee. I try to just fight through it. There's so many people standing around waiting for you to do your thing. You feel sort of obligated not to let everyone down."
Hemsworth plays Gale Hawthorne in the upcoming film, alongside Jennifer Lawrence, Josh Hutcherson, Phillip Seymour Hoffman, and Jeffrey Wright.
The Hunger Games: Catching Fire, which recently began shooting in Atlanta, is due for release in November 2013.
